Application filed May 16,18911 Serial No. 393,044. (No model.)

T0 all whom, it may concern:

Be it known that I, WALTER L. DAvIs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Motors for Propelling Cars; and I do hereby declare that the following is a full, clear, and exact description of the inventon, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, forming a part hereof, in which* Figure l is a top or plan view showing the frame-work and wheels lof a car with the propelling mechanism applied thereto. Fig. 2 is a side elevation showing the frame-work of the car in section. Fig. 3 is a face View of one of the barrels withits power-spring. Fig.. 4 is an edge View showing one of the barrels in section and the other in elevation. Fig. 5

is a face view showing the winding mechan' ism for the power-springs. Fig. 6 is an elevation. with the winding-wheel in section. Fig. '7 is a detail showing the 'manner of inserting and connecting the arbors for the spring.

The object of this invention is to construct a motor especially adapted for use in propelling street-cars, but which can be applied to and used for propelling cars or vehicles, and which will have the requisite power to produce the propulsion and have such power retained and utilized as required for actual use; and the nature of the invention consists in concentrating the power of a number of springs onto a single driving-wheel and transmitting the power thus concentrated to the axle for rotating the axle and propelling the car; in providing a power-transmitting mechanism between the main drive-wheel and the axle, which mechanism can be thrown into and out of use without impairing the operation of the power-producing mechanism; in providing means for holding the power-transmitting mechanism and releasing the connecting-gear for the axle at one and the same time and in releasing the'power-transmitting mechanism and engaging the driving-'gear for the axle therewith at the same time; in providing means for engaging and disengaging the power-transmitting mechanism with the power-imparting mechanism, and in the several parts and combinations of parts hereinafter described, and pointed out in the claims as new.

In the drawings, A represents a barrel, formed, as shown, of a back plate a with an annular wall or rim a and a face-plate a entering the wall or rim ct, so as to form a barrel with a chamber for the reception of the power-spring, and, as shown, eight barrels A are used; but the number of barrels can be four or more than eight, as required for the power desired.

B is an arbor for each barrel A, and each arbor is formed of a center portion b for the attachment of the inner end of the powerspring and with end journals b', on which the plates a and a are mounted, so that the barrel A is free to turn or revolve on the journals b from the power of the spring.

C is a power-spring, one for each barrel A, and each springis secured at its outer end by a pin c or otherwise to the wall or rim a', and each spring is secured at its inner end to the center b of the barrel B by a suitable pin c or otherwise, so that the spring will lie in the barrel Abetween the arbor B and the wall a'.

D is a squared shaft carrying the arbor B, each shaft, as shown, carrying two arbors B and two barrels A, and the arbors are inserted in two adjoining barrels on the same shaft D by inserting each arbor from the-'faceplate side ofthe barrel, with the face-plate removed, to have the portion of each arbor in the chamber of the barrel, and then inserting the 'squared shaft D through a squared hole in each arbor B, so as to lock each arbor to the shaft, and, as shown, the abutting ends b of the two arbors are connected together by a clutch connection b.

The shaft D, as shown in Fig. 7, extends from the end of the arbor B upward; but, asA shown in Figs. 2 and 4, the arbor end is carried upward and incloses the shaft; but with either form of construction the arbors B have a firm connection to the shaft and one to the other, so that both arbors will turn simultaneously with the winding up of their powersprings.

The arrangement shown for mounting the barrels has two barrels on each shaft D, the two barrels on the same shaft being in close proximity one to the other, so as to bring the gear of the barrels side by side and close together, thereby enabling the gears of the several barrels to occupy parallel planes in closeproximity one to the other.

E is a gear on the periphery of each barrel A, which gears for the two barrels on the same shaft D lie close together, as shown in Fig. 2, and these gears are formed with or firmly secured to each barrel, so as to travel with its barrel from the power of the spring.

J is a shaft onwhieh the pinion I is mounted, so as to slide longitudinally of the shaft and be locked with the shaft, so as to revolve therewith, the sliding of the pinion I on the shaft J being for the purpose of throwing the pinion into and out of mesh with the main drive-wheel H, and J is a shaft, on which is mounted the pinion I for the pinion to slide longitudinally of the shaft aud be locked thereto, so as to revolve the shaft, and the sliding of the pinion I on the shaft J is for the purpose of throwing the pinion into and out of mesh with the main drive-wheel H.

K is a gear-wheel on the shaft J, which wheel is formed willi or firmly secured to the pinion I and slides longitudinally on the shaft J and is locked to such shaft, so as to revolve therewith, and K is a gear-wheel on the shaft J, formed with or secured to the pinion I and sliding longitudinally on the shaft J and locked to such shaft, so as to revolve therewith.

L is a pinion meshing with the gear-wheel K, and L is a pinion meshing with the gearwheel K. The gear K meshes with the pinion L when the pinion I is in mesh with the main drive-wheel ll, and the gear K is out of mesh with the pinion L when the pinion I is out of mesh with the main drive-wheel ll, and the gear K meshes with the pinion L when the pinion I is in mesh with the main drive wheel Il, and the gear K is out of mesh with the pinion L when the pinion I is ont of lnesh with the main drveavheel ll. The piuion I and gear K are thrown ont of mesh with the main drivewheel II and the pinion L by means of an L-lever d, pivoted to a support by a pin or pivot d and having in its long arm a slot e, which receives a pin f, projecting from the hub g of the gear K, and the short arm of which has attached thereto a rod h, so that by moving the rod 7L the long arm of the lever (l will be thrown up, raising the gear K and pinion I by the engagement of the slot c with the pin f, and the pinion I and gear K are thrown outof mesh with the main drive-wheel Il and pinion L by an L-lever d, having a slot e in its long arm engaging a pin f, projecting from the hub f/ of the gear K and having a rod 7i running from the short arm of the L-lever in the same manuel' as the corresponding parts for raising the gear K and pinion I and operating in the same way.

M is a shaft on which is firmly mounted or secured the pinion L, and M is a shaft on which is firmly mounted or secured the pinion L.

N is a worm-gear firmly mounted or secured on the shaft L, and N is a worin-gear firmly mounted or secured on the shaft M. The pitch of the worm-gears N and N are opposite-thatis, one of the gears has a right-hand pitch for its thread and the other has a lefthand pitch for its thread.

O is a'gear meshing with the thread of the R is an upper frame-work, and R a lower I frame-work for supporting the power mechanism, and each framework is formed of end bars, intermediate bars, and a central longitudinal bar, as shown in Figs. l and 2, and, as shown, the shafts D are supported at the upper end in the intermediate cross-bars of the frame-work It, the shafts M and M are supported in the end cross-bars, and the shafts J and J are supported in the longitudinal center bar, and these shafts at the lower end are supported in the corresponding bars for the framework R.

S are side pieces of the frame of the car, to which is secured the upper frame-work R, and S are two of the crosspieces of the carframe.

'l is a lever, one at each end of the car, and each lever is pivotally connected with a support T', secured to the cross-piece i" at the end of the car by a suitable pin or pivot fm, and each lever 'l at its innerend has a fork Z, cach arm of which has a slott to receiveapin projecting from the hub or center i' of the gear O or the gear O', so that by moving the lever 'l for the gear-wheel O or O such wheel will be thrown out of mesh with its wormgear N or its worm-gear N.

U is a shaft at cach end of the car, having at the upper end a suitable hand-wheel or handle (not shown) by which the shaft can be turned, and each shaft U has firmly secured thereto an arm o, which is connected by a link n with the outer end of the lever T,

so that by turning the shaft U the arm 0 will through the link 'n move the outer end of the lever T for the inner end of such lever to throw the gear-Wheel connected therewith into or out of mesh with its worm-gear. The shaft U at its lower end has iirmly secured thereto a grooved wheel p, to which is attached one end of a chain q for winding the chain q on the wheel @and the inner end of the chain q is attached to the end of a iiat spring r, which spring winds around a drum s and has its end attached to a pin tor other connection on the lower frame-work R', and a drum s is formed with or suitably secured to the wormgear N and to the worm-gear N', and abrakespring r, Winding-chain q, and winding-wheel p are provided for each drums.

V is a gear-wheel having a hub or center e with a journal, in which is a key-hole fv', and the hub or center u on its periphery has ratchet-teeth w engaged by a ratchet cc, which ratchet is held in engagement by a spring y. This gear-wheel V meshes with four pinions W, one pinion for each shaft D, and each pinion is firmly secured to its shaft, so that by turning the wheel V the pinions NN will be turned, turning the shafts D and revolving the arbors B to wind up the several powersprings C. The wheel V is located in suchrelation with the main drive-wheel H asto have its hub o in a central line with the shaft G of the main drive-wheel H, and the lower end of the shaft G is stepped or mounted in the center or hub v, as shown ih Fig. 6, so that the shaft G is free to revolve without revolv.- ing the gear-wheel V, and the gear-wheel V can be turned without turning the shaft G, the result being that the springs can be wou nd up without aifecting the vmain drive-wheel and the main drive-wheel can revolve without affecting the winding mechanism.

The arbor B is slipped into its barrel A with the face-plate a" removed, and the spring C is attached by the pin c to the wall a' and by the pin c' to the centerh of its barrel, and when inserted the journal ends b' of each barrel will project, one through the plate a and one through the plate d", mounting the barrel on the journal ends, and when two or more barrels are mounted on the same shaft D the abutting journal ends h' of each arbor B has a clutch b" for engaging and-locking one end with the other, so as to lock the two companion arbors B together, and the shaft D, when the clutch h is engaged, is passed through both arbors, locking the arbors to the shaft D and bringing the gears E adjacent one to the other, as shown in Fig. i, and the lower journal of the lower arbor B has a squared center or hub to receive the winding-pinion W, and below this squared hub the end of the shaft D is rounded to form a journal for the lower end of the shaft. The barrels mounted on the shafts D are set side by side, as shown inFig. 4, around the Windingfwheel V for the winding-pinions 'W to engage such wheel,`as shown in Fig. 5, and the hub orcenter o has its journal mounted in thelongitudinal bar of the lower frame-Work R', and the journal for the lower end of each shaftD is inserted in holes therefor in the cross-bars of the lower frame-work R', arranging the barrels around the center of the wheel V and equidistant therefrom. The shaft G, with the pinion Fand gear-wheel H thereon, is entered between the gears E on the several barrels for the pinion F to mesh with each gearE, as shown in Fig. l. The shafts M and M are entered at their lower ends in holes therefor in the end bars of the frame R, each shaft having thereon its driving-pinion, worm-gear, and drum s. The shaft J, with the gear K and pinion I mounted thereon, has its lower end inserted in the hole therefor in the central bar of the lower frame-work R' for the pinion I to mesh with the main driving-gear H and for the gear K to mesh with the pinion L of the worm-wheel N. The shaft J', with the pinion I' and gear K thereon, has its lower end inserted in the hole therefor in the central bar of the lower frame-work R' for the pinion I to mesh with the main drivinggear H and the gear K' to mesh with the pinion L' of the worm-gear N', and the upper plate or frame-workRis placed in position to receive and support the several shafts and hold the mechanism, as a whole, in proper connection, The L-levers d are pivoted to the frame-work to have the slot e in the end of the long arm of lever engage the pin f on the vhub g of the respective gears K and K', and

the rods hare connected with the short arm of each lever. to have the rod h for the lever d,

IOO

which moves the gear K, run to the opposite end of the car from the gear, and the rod h for 'the bell-crank lever d of the gear K' run to the opposite end of the car from the gear K', as shown in Fig. 2. The gears O and 0 for the axles are mounted each on its axle, so as to slide thereon longitudinally and be held thereto by a spline or otherwise, and the axles, with the wheels Q, are set to have the gear O engage with the worm-gear N and the gear O'engag with the Worin-gear N', `which completes the connection of the power mechanism with the running-gear for the car. The levers T are each pivoted to the arm T' therefor. by the pin or pivot m to have the fork Zstraddie the hub or center 1'-, with the pinj in the slot 7c of each arm of the fork l, and the outer end of each lever T is connected by the link n with the arm o, attached to the shaft U, which shaft is mounted in suitable bearings on the carframe and is locked by a suitable dog or clutch u, or iu any other well-known manner. The wheel p is attached to the lower end of IIO the shaft U and the chain q attached thereto.v

the frame-work for the power mechanism attached to the ear-frame the motor, t s a whole, is mounted on the car and is ready for use.

The length of the spring fr and its relation to the drum s and the wind of the chain q onto the wheelp with the movement of the arm o are coequal, so that the lever T will slide the driving-gear connected therewith out of engagement with the worm-wheel coincident with the application of the brake-band r to act on the drum s and hold the wormgear, and the release of the brake-band /r from its drum s is coincident with the sliding of the axle gear into engagement with its worm-gear by a reverse movement of the shaft U, the result being that the application of the brakeband r to its drum s is coincident with the movement of the lever T, so that as the brakeband acts and stops and holds the worm-gear the lever acts and carries the axle-gear out of engagement, and as the brake-band releases the gear is carried into engagement, by which arrangement it will be seen that the wormgear is held by the brake-band when released from the axle-gear and is held by the axlegear when released by the brake-band, and this arrangement prevents the worm -gear from being at any time released, so as to be revolved from the power Of the springs, except when engaged with the axle-gear. The rod t, running to the opposite end of the car from that on which the gear moved by the rod is located, prevents any displacement of the gear, as when the operator leaves the platform he, through the rod h, throws into use the gear which has been ont of use, and cannot throw the other gear out of use until he reaches the opposite platform, by which arrangement the connecting-gear between the main drive-wheel and the worm-gear which is brought into use must be the one which will operate the worm-gear to propel the ear in the direction required.

In use, as shown in Figs. l and 2, the car is propelled in the direction of the arrow in Fig. l, and with the car traveling in this direction the driving-axle gear 0 is engaged with the worin-gear if, and the pinion L is engaged with the gear K, and the pinion I is engaged with the main drive-wheel II, while the pinion Il and gear K are disengaged from the main drive-wheel and the pinion L. The barrels A all revolve toward the center wheel F and in the direction of the arrows shown in Fig. l, and such rotation of the barrels is had by reason of the release of all the springs to the center, which rotates the barrels A on their journals l), and such rotation of the barrels carries with them the gears E, connected one to each barrel, and these gears transmit their united power onto the center wheel or pinion G, with which they mesh, revolving such wheel in the direction of the arrow shown in Fig. l, turning the shaft G correspondingly and driving the main wheel H in the same direction, as shown by the arrows in Fig. l, and this rotation of the main wheel @rasee Il, when such wheel is in mesh with the pinion I, turns such pinion in the direction of the arrow in Fig. l, rotating the shaft J in the same direction and driving the wheel K correspondingly, as shown by the arrow in Fig. l, and such rotation of the wheel K drives the pinion L in the direction of the arrow in Fig. 1, rotating the shaft M in the same direction and turning the worm-wheel N likewise, as shown by the arrow in Fig. l, which rotation of the wheel N by its engagement with the axle-gear O turns such gear in a forward direction, as indicated by the arrow in Fig. l, revolving the axle P and wheels Q of suoli wheel O forward and propelling the ear.

The car will travel in the direction indicated by the arrow in Fig. l as long as the gear K is engaged with the pinion L and the pinion I is engaged with the main drivewheel ll, and to reverse the travel of the car the operator leaves a front platform engaging the gear K and pinion I before leaving and goes to the rear platform, which then becomes the front platform, and throws the gear K and pinion I out of mesh with the pinion L and main drive-wheel II, and also throws the axle-gear O into mesh with the worm-gear N, releasing at the same time the brake-band i' from the pulley or drum s, and having released the axle-gear O from the worm-gear N on leaving the first platform, and at the same time applied the brake-band i to the pulley or drum S of the worm-gear N, the worm-gear N becomes the driving-gear for the car, and with this connection the bal'- rels A, gears E, pinion G, and main drivewheel ll revolve in the same direction, as indicated by the arrows in Fig. l, and the driving-wheel II transmits power to the pinion I', revolving such pinion in the direction of the arrows in Fig. l, and through the shaft J revolving the gear K' in the direction indicated by the arrow in Fig. l, which gear, meshing with the pinion L', drives such pinion in the direction of the arrow in Fig. 1,'and through the shaft M rotates the gear N in the same direction, as indicated by the arrow in Fig. l., and as the thread of this worm-gear has the opposite pitch to that of the thread on the worm-gear N such worm-gear acts on the axlegear O and revolves such gear in the direction of the arrow in Fig. l, which is the opposite direction to that of the axle-gear O, and such revolving of the axle-gear O revolves the axle I and wheels Q of the gear O in the same direction as the gear O', thereby propelling the car in the opposite direction corresponding to the travel of the gear O and its axles and wheels.

The springs are graded each to a certain power, so that their united foree, transmitted onto the center or main drivingwheel II through the pinion F, will unite the power of all the springs onto the main drive-wheel for transmission 'through the ,connecting-gears to the axle for propelling the car, and the united IIO power of all the springs is one to produce the required speed for the distance desired for the car to travel, as in propelling the car under a certain speed and for a given distancel only so much power is required, and this power will be taken from all the springs, releasing the spring as a whole to the limited extent required for the speed and distance in a certain time, instead of releasing the entire power of a single spring, and therebya longer distance of travel is assured with the united power of a number of springs transmitted to a single drive-wheel than with the power of a single spring transmitted to the same wheel. The springs are wound at the terminal of theline or at such other point as may be desired, and to wind the springs a key or shaft is inserted in the holen of the hubVand powerapplied to turn the key or shaft, which turns the hub and revolves the gear and winding wheel V,- and such wheel,by meshing with the pinions NV of the several shafts D, revolves such winding-pinions simultaneouslyand turns all ofthe shafts at one and the same time simultaneously winding up all of the power-springs C for the several barrels A, and when the springs are completely wound all the springs are held by the single dog x, engaging with the ratchet w, which locks the hub 'u and thereby locks the gear or winding wheel V, and with such wheel stationary the pinions W are all locked andY the shafts are held stationary, holding the several barrels B stationary, so that with a release of the power mechanism to propel the car each spring C must release to the center, propelling the several barrels in the same direction to apply the power of the several springs to the main drive-wheel. v The winding of the power-spring up does not affect the power mechanism, as the wheelV is free to turn without turning the shaft Gand with the wheel V locked by the dog and ratchet w the shaft G is free to turn without affecting the winding mechanism, the result beinga winding up of the springs without effect on the power-transmitting mechanism Iand the operation of the power-transmitting mechan ism without effect on the winding devices.

The connecting-gear between the two wormgears and the main power-wheel His operated from opposite ends of the car, and with the car traveling in the direction of the arrow in Fig. l the con necting-gear for the worm-wheel N is out of engagement and the connecting-gear for the worm-wheel N is in engagelnent, and the operator, standing on the l for the worm-wheel N through the rod h and the bell-crank lever d, and in leaving the platform X when the car is at the end of its running the operator throws the connectinggear for the worm-wheel N into mesh, so that at this time the connecting-gear for the wormwheel N and the connecting-gear for the worm-wheel N will bot-h be in mesh with the wheel and with the connecting-gears, and with both in mesh the power mechanism will be locked and will so remain until one of the gears is disconnected. The connecting-gear for the worm-wheel N is out of mesh when the car isvtraveling in the direction of the arrow in Fig. l and the operator is on the platform X, and with the operator on the platform X the axle-gear O can be thrown into and out of mesh with the worm-gear N for driving or propelling the car, and when the operator leaves the platform X to mount the platform Xand run the carin the opposite direction to that in Fig. 1 he throws the axle-wheel O out of mesh with the wormwheel N, and at the same time the brakeband or spring r is applied to the hub or drum of the worm-wheel N, so as to firmly hold and lock such wheel against rotation, and the driver in mounting the platform X throws the axle-wheel O', which is out of mesh with its worm-wheel N, with the car traveling in the direction of the arrow in Fig. l, into mesh with its worin-wheel N, connecting the axle of the wheel O with the worm-wheel, and as the wheel N has been connected with the main drive-wheel H before the operatorleaves the platform X the power is connected so as to be transmitted to the axle of the wheel O', and when thedriver has engaged the wheel O with its worm-gear N he throws the connecting-gear for the worm-wheel N out of mesh, which leaves the power to be transmitted from the main drive-wheel H through the connecting-gear to the worm-wheel N and thence through the gear O to the axle of such gear and propel the car in the opposite direction to that in Fig. l. It will thus be seen that the power is locked and held whenthe car is at a standstill, and is released with the car moving in either direction, and when released the recoil of the springs is controlled by the power required to propel the car.

The stopping of the car requires the application of the power to cease on the axle-gear, and this is had with each stoppage by throwving the axle-gear out of mesh with its wormgear, which at the same time applies the brake-band to the hub or drum of the Wormgear and locks and holds the worm-gear, and it will thus be seen that the power is under control at all times by the operator.
